fering from an allied disease. Cows SO
! afflicted do not present any acute
symptoms, and the condition might be
easily overlooked unless carefully
watched. II is suggested that milk about
which there is any doubt should be
boiled, in oder to destroy disease germs
that may be present.
Though it is claimed as one of the ad.
vantagcs of electricity, that it does not
raise the temperature Of the atmosphere
when used for lighting, it is nevertheless.

IN future, in addition TO light, they will

The early Americans were representa-.
tlvcs of the stone age in most cases, nj.
though few possessed the knowledge OF
metals They were particularly clc,er
stone workers, and the samples of their
workmanship show them well verscd in
the arts of the potter. In cay-molding
they were also skilful. The textile arts
were praetiscd, such as cotton and wool
spinning and weaving. Cotton was ex-

The purity of the mid-Atlantic air has
been demonstrated by Professor f. S.
Dennis, of New York, by means Of cap
su!es of sterilized gclatinc, which were
exposed to it on the promenade deck,
where there was free circulation of the
atmosphere. In ten days few points of
infection were Developed When eX-
posed in one Of the state-rooms over 500
points of infection were developed within
eighteen hours, But when n capsI H. was
exposed over the bow of the ship it was
found to be entirely untouched. The OK
periments show how pure was the mid
ocean air outside the inclosed spaces of
the vessel
The new French incombustible lace is
quite novelty, and the composition by
which this result is achieved is equally
adapted, 1t seems, to rendering paper
and wool unintlammabe. 1t is mix
tlre of eighty parts pure sulphate of am
mona, twenty-five parts carbonate of
ammonia, thirty parts boracic acid, seven
teen parts pure boraX, twenty parts
starch, and one thousand parts distilled
orpurc water. These ingredients are
most thoroughly combined. The mate-
rails are dipped in this solution while
hot, so as to be completely impregnated,
after which they are dried and ironed as
ordinary starch fabrics.
